Sharing his experiential understanding of the classic Hatha Yoga Pradipika, Baird Hersey offers precise, step-by-step instructions on how to find the inner sound of the nada. He explains the first three levels of sound--first, how to truly hear the ordinary sounds of the world around us (vaikhari); second, how to quiet the sounds of the mind (madhyama), such as sound memories and internal dialogue; and third, how to access visual sounds (pashyanti), tapping in to our ability to see sounds and hear colors. Mastering the first three levels prepares one for the fourth level of sound (para), the heart of the practice that connects one to the inner sound of the nada. Hersey provides detailed exercises to guide you through each level of sound and instructions for a daily nada yoga meditation practice. He explains that by focusing our minds on this internal sound we reunite our essential self with the eternal and infinite. In this re-union we find bliss in both body and mind, an uplifted spirit, and heightened states of consciousness.
